Version	Date	Change	What changed
v2	2026-09-28	The ISO 14044 footnote now cites ISO 14044:2006 with a link and quotes the standard on normalization (section 4.4.3.2), on weighting as value choices (section 4.4.3.4.2), and on weighting not being used for public comparative assertions (section 4.4.5). It replaces a paraphrase that said only that the standard 'discourages' collapsing categories. The footnote is now also cited at the sentence on single-score columns.	prose — body (prose edited)

Editions are cut at publish time from a content hash of the entity's canonical source, so a version changes only when the content actually changed. Full canonical content for every edition, and the exact per-part diffs between them, are in the downloadable editions archive (editions_archive.jsonl); the current-state index is versions.jsonl.
